Review:
I got this game last week and am currently on chapter 9. Although i have not finished the game I think I have played it long enough to give a fair review. Graphically the game is great but then again portal 2 or even portal for that matter was never about the graphics... that's my opinion anyways.

Portal 2 takes place after the events of Portal. You wake up from a stasis sleep in what looks like a hotel room and are soon greeted by Wheatley a robot. He helps you you escape from the room which is in fact a storage container in what looks like a huge warehouse among thousands of other storage containers. Soon after you find yourself back at the Apertures Science facility. You play as the same character(Chell) as you did in the original portal, and solve puzzles or as the game prefers to call it "testing". I will leave this section at that since revealing any more would possibly spoil the game.

For the most part the gameplay is identical to the first portal. You are in first person shooter mode equipped with a portal gun that can shoot portals at certain places in the wall(mostly anything white) allowing you to teleport through them. You use these portals to solve puzzles in the room and try to get to the exit, and then move to the next room and repeat. One of the key things about these portals is that you maintain your speed as you travel through them. So for example you could shoot a portal on a wall, jump off a high place, and right before you land shoot a second portal at the ground. As a result you will launch out of the first portal you shot in the wall and be able to reach places you would normally not be able to reach. There are a few additions that were not in portal for example the gels, tractor beams, light bridges/walls, laser redirection, and aerial faith plates. there are 3 types of gels you will find throughout the game that can be painted on various surfaces: Repulsion gel (blue) makes you bounce on contact, Propulsion gel (orange) boosts your speed on contact, and Conversion gel (white) which lets you shoot a portal on a surface you would normally not be able to shoot a portal on. The tractor beam does exactly what you would think it does by pulling or pushing anything(objects/yourself) that gets caught in it. The light walls or bridges depending on how you use them create either a bridge for you to walk on or a barrier to stop you as you fly across the room. The laser redirection again does exactly what it sounds like. It is basically a cube with glass on the surface and can be used to redirect a laser in order to activate a platform or an exit to a room. The aerial faith plates when stepped on launch you across the room. The goal is to use a combination of these depending on which room you are in and try and get to the exit

The voice acting in the game is what really shines. From GLaDOSs'(voiced by Ellen McLain) insults, to Wheatleys'(voiced by Stephen Merchant) constant sillyness, to Cave Johnson(voiced by J.K. Simmons) strange recordings that will leave you wondering what went on in Aperture Science Laboratories. In my opinion Stephen Merchant pretty much steals the show as you will be laughing throughout the entire game. This is probably the only time in a game I have thoroughly enjoyed everything being said by the game characters.

There is a co-op aspect to the game as well. Two players play as robots equipped with portal guns and have to work together to solve puzzles and get to the exit. Co-op play requires that both players actively play and work together. In other words if one person is being lazy or doesn't want to work on getting to the exit the puzzle becomes impossible to solve. I have not played the co-op part of the game extensively so I don't have much to say about it, but it is there and from the looks of it is a great way to continue playing after you finish the single player part of the game.

Conclusion: Regardless of what genre of game you prefer playing any gamer will thoroughly enjoy portal 2. The puzzles are hard at times but never become frustrating to the point that you feel they are unsolvable. The longest I found myself stuck in a room was probably 30 minutes. And with what is probably the best voice acting ever in a video game you will never find yourself bored as you play. It's amazing what started off as an add-on to the original half life series in the orange box collections has made a come back as a stand alone game and is shaping up to be one of the best games of 2011.
